COMBUSTION-PROMGTING DEVICE.
Application led September G, 1922. Serial No. 586.466.
T all lwho/ml t may concer/IL.'
Be it known that we, THOMAS F. LAW- TER and Anm H. LAw'rnn, citizens of the United States, residing at Newcastle,'in the county of Henry and State of Indiana, have invented new and useful Improvements in CombuStien-Promoting Devices, of which the following is a specification.
Our present invention has reference to a heating plant.
Our object is to provide in a stove or furnace a means for admitting air into the fire box thereof, causing such air to be heated and the heated air delivered downwardly on to `the burning coals to mix with the gases therefrom, and thereby greatly promoting combustion, and consequently obtain a greater heat with a smaller consumption of fuel.
rEhe foregoing, and other objects which will present themselves as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification. Y
In the drawings Figure 1 is an approximately central vertical longitudinal sectional view through a heating plant, such as an ordinary furnace, provided with the impro-vement.
Figure 2 is a sectional view on the line 2 2 of 'Figure l.
Referring new to the drawings in detail, the numeral l designates a heatingfplant, such as an ordinary furnace. ln the furnace, and extending centrally from but secured a slight andV suitable distance above the grate 2 there is a drum 3. The drum is gradually flared inwardly from its lower open end to its top, the open end of the said drum being so positioned that air from the ash pit will enter lthe drum. The open end of the druni may be provided with outwardly directed ears'flwhich are secured in any desired. manner in the furnace for supporting the same. The drum 3,l at its reduced upper end is provided with a tubular extension 5, and on this extension there is formed a hollow head 6. The head 6 `is the nature of an air mixer and the walls constituting the same are concave-convex 1n cross section, the upper and lower walls being connected by a rounded wall or edge 7,
andthe said wall or edge is provided with spaced apertures 8 whereby heated air from the mir-ing chamb r or head 6 will be delivered downwardly on to the burning coals.
Connected to the drum preferably at the juncture of the pipe or tubular extension 5 with the conical end thereof, there is a cold air inlet pipe l0, the said pipe extending through one of the sides of the furnace and if desired, this pipe may communicate with the outer atmospheric air.
lt is thought that the foregoing description, when taken in connection with the drawings will fully set forth the construction, operation and advantages of the improvement to those skilled in the art to Vwhich such inventions relate, it being apparent that the live coals will effectively heat the drum and the elements associated therewith, that cool air will enter the drum through the pipe l0, that the said air will circulate through the pipe extension 5 into the mixing chamber 6 and will be from thence delivered through the restricted apertures in the head or mixing chamber downwardly on to the live coals, thereby materially increasing combustion and also thereby obtaining a greater amount of heat from a less consumption of fuel.
Having described the invention, we claim:
The combination with a heating device, of a flared drum having its widened end open and arranged above the grate of the heating device, said drum having at its restricted end a tubular extension which terminates in a hollow head, the opposed walls of the head being roundedV from the center thereof downwardly and being connected by a rounded edge which is apertured on the under face thereof and a cold air conducting pipe extending through the heating device .and connected to theV tubular extension.
InV testimony whereof we our signatures.
THOMAS F. LAWTER. ALVA H. LAVTER.
